Mobility of exchangeable cations in soil treated with Ca-sulfate, Mg-sulfate or K-sulfate


, : Mobility of exchangeable cations in soil treated with Ca-sulfate, Mg-sulfate or K-sulfate. Annals of Agricultural Science, Moshtohor 34(3): 1345-1357

The effect of Ca-sulfate, Mg-sulfate or K-sulfate applied at equivalent rates to the top of soil column was assessed on the recovery of Ca, Mg, K and Na in leachates and on their mobility within soil columns. The changes in concentrations of exchangeable cations in leachates corresponded to the changes in ionic strength (I). The effect of the amendments on recovered Ca was: K-sulfate > Mg-sulfate > Ca-sulfate (R2) > Ca-sulfate (R1).
